Thank you to Avery C. (Aspire 16) for alerting us to this video summary of Immunity to Change. If you want a quick re-introduction to the concepts, or even to the worksheet, here is Dr. Robert Kegan himself, the author of the book and the designer of the program. Avery comments: "The video is short (14 minutes on YouTube) and Dr. Kegan is a good speaker: funny and interesting."
